What kind of wives can be beaten?

I was doing some Google Video hunting and came across an interesting video....

Types of wifes that can be beaten, according to the Koran

"...and because when you purchase an electric appliance or a car you get a manual...explaining how to use it. The Creator of Man had sent down this book (the Koran) in order to show Man which ways he must choose". Apparently we in the West are still in our "days of ignorance" and can't acknowledge the "wondrous verses" that explain when we can beat our wives.

And then by clicking on the related videos area I found this one...

Cat Stevens signing "Hard Headed Women"

Cat Stevens has gone by the name Yusuf Islam after he converted to Islam in 1977, which explains why it was only a couple related videos away from the other one.
